Wiper Arm Maintenance

[HarborBus]

FYI, On our tip home this spring we had one of our wiper arms loosen up and after flopping around loose it damaged the spline inside the arm. These are aluminum so fortunately it damaged the arm splines and did not effect the stainless post splines on the bus. The wiper arms are supposed to be torqued to 22 ft lbs I think it would be a good idea to add this to everyone's PM list as the arm from Prevost is $254.00 Does anyone know of a source for these other than Prevost?
